"Custom" theme after returning from Hibernation

[Yaron]

Hello,

STR:
Apply "Test Theme".
Hibernate (NOT Sleep).
Turn your machine ON.

Result:
Windows Settings -> Themes: the active theme is "Custom" instead of "Test Theme".

This causes some issues in various programs.
For example: in Firefox 89 (Proton enabled), the color of menuitem[disabled] is black and I need to draw it manually in userChrome.css.

Any idea how to fix it?

Thank you.

That has fixed it. You're the best!

Interestingly, Firefox seems to use the color of "Lists, Menus, & Tabs > Context Menu > BarItem > Disabled" for the context-menu.
(Instead of "Lists, Menus, & Tabs > Context Menu > PopUpItem > Disabled").
